In order to study the effect of row space and seed rate on yield and component yield and agronomy characteristic of RGS003 Var. In Moghan region .This experiment was condition in moghan agricultur research center during 2005-2007 .The experimental design was split block based on randomized complet block design ,with 4 replicationThe main plot included row space (12.5 and 25 Cm.) and 3 seed rate (5 , 7 and 9 kg /ha) assigned to the sub plot. Combined analysis of 2 years showed that the row space and seed rat on seed yield in rapeseed significant. In the experiment was row space 25 Cm. with yield (3190.4 kg/ha) and 12.5 row space yield 2768.4 kg/ha in duration 2 years. There was significant different between seed rate.7 kg/ha seed rate was highest grain yield in this experiment. 7kg/h seed rate was grain yield 3246.25kg/ha . response of grain yield to row space and seed rat in RGS003 Var. Rapeseed was different and interaction of row space * seed rate showed significant different on 1% probability. Second year in this experiment * 7kg/ha was highest grain yield (3353.25kg/h) and in first yiare treatment of 9kg/ha seed rate lowst grain yield (2287kg/h) in duration of second year in this experiment was grain yield in 25 centimeter 2982.4 kg /ha and 7kg/h seed rate was highest grain yield(3139.2 kg/h).
